Which echocardiographic view is most helpful to view a VSD in the inlet position?

Answer: Apical four-chamber view

Explanation: As an inlet VSD is positioned directly below the mitral and tricuspid valves, there is no tissue border between the defect and the atrioventricular valves. As such, there is typically lack of offset of the tricuspid valve towards the apex of the heart. This is best appreciated in an apical four-chamber echo view as mitral and tricuspid valves are seen at the same level instead of the tricuspid valve being slightly lower than the mitral valve. Therefore, this is a good clue to suggest that the VSD is in an inlet position. The subcostal and parasternal views are less helpful than the apical four-chamber view as the inlet portion of the ventricular septum may be difficult to appreciate. The parasternal short-axis view can be helpful as the VSD is seen in the posterior portion of the septum in the same plane as the AV valves.
